I can provide information about Shankar's textbook "Quantum Field Theory and Condensed Matter."
"Quantum Field Theory and Condensed Matter" by Shankar is a highly regarded textbook that explores the intersection of quantum field theory (QFT) and condensed matter physics. The book is written by A. Sudbery, not to be confused with R. Shankar who authored "Principles of Quantum Mechanics," another well-known textbook.
Shankar's book offers a comprehensive introduction to the field, covering topics such as second quantization, the path integral formulation, and the application of QFT techniques to various condensed matter systems. It delves into concepts such as renormalization group, spontaneous symmetry breaking, topological phases, and more.
Many students and researchers consider Shankar's book to be a valuable resource for learning about the connections between quantum field theory and condensed matter physics. It is known for its clear explanations, detailed derivations, and extensive coverage of the subject matter. The book strikes a balance between theoretical rigor and accessibility, making it suitable for both graduate students and researchers in the field.
However, as with any textbook, different individuals may have different preferences or learning styles. It can be helpful to read reviews, consult with peers or instructors, and explore multiple resources to find the learning material that best suits your needs and preferences.
